Google Glass entered the operating room on June 20 when Dr. Rafael Grossman, surgeon at the Eastern Maine Medical Center in Bangor, in the U.S., performed a gastrostomy, namely the placement of a feeding tube into a patient's stomach, with his Google Glass in tow. The surgeon wore a Google Glass frame throughout the operation and the images captured by his eyes were projected onto an iPad display. The procedure was streamed live to a Google Glass Hang-out, the function that enables group conversations. In his blog, Dr. Grossman specified that video and photo streaming never revealed the patient's identity or face and that every precaution was taken to ensure the protection of the patient's privacy. Functionality and privacy are Google Glass issues that were already talked about months before the device came on the market. Dr. Grossman said that, to his knowledge, it was the first time that Google Glass had been used in an operating theater, paving the way to easy team consultations and teaching through this new device.
